About Bladder Cancer

Most bladder cancers are transitional cell carcinomas Other types include squamous cell carcinoma and adenocarcinoma. The cells that form squamous cell carcinoma and adenocarcinoma develop in the inner lining of the bladder as a result of chronic irritation and inflammation. Cigarette smoking and exposure to solvents are key risk factors for bladder cancer. Other risk factors include: personal and family medical history, exposure to certain parasitic infections, and a history of having been medically treated with cyclophosphamide or arsenic.

 

Bladder cancer is the second most common urologic cancer (after prostate cancer). Bladder cancer occurs more frequently among the elderly: the median age for diagnosis of bladder cancer is 73, and 72% of people diagnosed with bladder cancer are 65 or older.
